BUNG-SEAL.

Specification of Letters Patent.

Patented Nov. 21, 1916.

Application fi1ed September22, 1915. Serial No. 51,987.

To all whom it may cancer-n.

Be it known that we, CARL ZANG and JAMES H. Sownn, citizens of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Bung-Seals, of which the following is a specification.

The present invention relates to a bung for barrels, kegs, or the like, having means for holding or locking it in the bung hole, rendering it exceedinglv difficult, if not impossible, to move the bung without detection.

An important object of the invention is to provide means of the above mentioned character, which are simple in construction, inexpensive to manufacture, and convenient in use.

A further object of the invention is to provide a bung of the above mentioned character, having a recess adapted to receive a plug which closes the recess and is adapted V to bear a trade-mark or name.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of the bung, Fig. 2 is a horizontal sectional view taken on line 22 of Fig. 1, Fig. 3 is a central vertical sectional view through the same, and Fig. 4 is a view similar to Fig. 1, showing the plug in place. In the drawings, wherein for the purpose of illustration is shown'a preferred embodiment of the invention, the numeral 5 designates a portion of the barrel having a bung hole 6, which is preferably tapered and decreases in diameter inwardly. This bung hole is adapted for the reception of a bung 7 which may be formed of wood although other suitable material may be advantageously employed. The bung 7 is provided preferably centrally thereof with a preferably cylindrical recess 8, the bottom wall of which is provided preferably centrally thereof with a notch or recess 9. Leading into the recess 8 are openings 10 which are permanently formed in the bung and are preferably disposed in parallel relation.

Mounted to reciprocate freely within the openings 10 are pins or prongs 11, the outer ends 12ofwhich are preferably sharpened and are adapted'to penetrate the wall ofthe Opening'G. The inner ends of the pins 11 project for a substantial distance into the recess 8.

The numeral 13 designates the body por tion of a key, provided at its outer end with a transverse hand grip 14 by means of which the key may be turned. Rigidly mounted upon the inner end of the body portion or shank 13 is a double ended cam 15, spaced a slight distance from such inner end, whereby a projection 16 is provided, adapted to be pivotally mounted within the notch 9 for forming a turning point for the key. As shown in Fig. 1, the double ended cam 15 is adapted to be inserted within the recess 8 with its end portions arranged in contact with the ends of the pins or projections 11, and when the key is turned in the proper direction this cam will move the pins or prongs 11 outwardly, so that the pointed ends 12 thereof enter the wall of the recess (3, thus locking the bung in place.

In Fig. 4:, we have shown a plug 17 arranged within the recess S, and this plug preferably carries a trade-mark or name for the bung. The plug may be formed of wood, waX, or other sealing material and when the plug is formed of wood or the like it may be sealed in the recess.

From the foregoing description the operation of the apparatus is believed to be obvious and no further description thereof is deemed necessary.

It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described our invention, what we claim is:

A bung provided with a main opening extending through its outer end to a point spaced a substantial distance from the inner end and provided in the bottom of this opening with a pivot recess and having openings passing through the periphery of the bung and leading into the main opening, pins mounted to reciprocate within the last named openings and having their outer ends pointed to enter the material of the ed upon the body portion and spaced a substantial distance from the free end thereof and adapted to contact with the pins; and a sealing plug adapted to be mounted With- 10 in the main opening whereby the pins cannot be manipulated Without the sealing plug being partly or wholly destroyed.

In testimony whereof We aflix our signatnres in presence of tWo Witnesses V CARL ZANG.
